How Much Air Pressure Should Dentists Use for Dental Handpiece?

Good usage habits can prolong the lifespan of dental handpiece, and also can bring professional treatment and comfort to patients.
Some dentists who use China dental handpiece with more than the specified air pressure in order to speed up the treatment process, which leads to faster wear on bearings of the dental high-speed handpiece.What’s more, the supported cage of the bearing will be damaged due to excessive load, resulting in a shortened life span of the entire dental handpiece and even medical injuries.
These are the most common failures of dental handpieces caused by the use of excessive air pressure.

So is it possible to use lower air pressure? Let’s see what will happen when using higher and lower air pressure?
1.Use higher air pressure
When we use too high air pressure, the great load will make the bearing of dental high speed turbine wear out extremely fast. The life span is greatly reduced.
2.Use lower air pressure
Dental handpieces will rotate weakly, increasing the load of torque and damaging the bearings!

Good usage habits can prolong the lifespan of China dental handpiece, and also can bring professional treatment and comfort to patients. We recommend that dentists use the correct air pressure and speed range as follows.
Different brands of dental handpieces like NSK dental handpiece, KAVO dental handpiece and SIRONA dental handpiece, they have different air pressure requirements, and only use within the manufacturer’s specified air pressure range will ensure the best performance of the dental handpiece.
Brand | NSK | KAVO | SIRONA |
Air Pressure: Mpa | 0.22-0.25 | 0.23-0.27 | 0.22-0.28 |
If there is no special air pressure meter to measure, we can generally counting the loss of dental chair piping, the air pressure on the dental chair table is set to about 0.28Mpa, do not pursue high torque output to adjust the air pressure up.For more details to maintain dental handpiece, you can refer our previous articles.
